Always the paranoid one... I believe the fins are Nibral (Nickle, Bronze, Aluminum alloy) like many of the props. If this is the case, then the dust caused by grinding is toxic...use a respirator.

If they are Bronze, then I do not believe there is a health risk in grinding.

Fin straightning.
You can send it to a prop shop.
You can try it yourself, be carefull.
Do not heat it, severe cracks below the forging temp, saw some ruined ones due to low temp.
Did mine cold worked, large nylon hamer or hammer with aluminum heads, use hardwood underlay or solid aluminium of nylon underlay.
Do not use steel tools this will mark the fin, the bronze is very soft,when you can regrind it. Press can be used but a fin is diffecult to handle because of the radis through taper
of the fine.
Did mine which where quit soft.
Succes.

Dan, I straightened mine out (after I dropped the boat on the ramp) by using a "hydro-press" (bearing press should work). I just laid the fin down on its side, lined up the press in the middle of the fin then let her rip. I had to do this several times to be sure I got her as straight as I could. It lines up with the other 2 fins with 1/4" or so. I can live with that.
